Differentially expressed genes in response to 50 kPa and 50 kPa/NormOx in roots of 10 d and 5 d plants. (A) Heat map of 221 differentially expressed genes with statistical significance (p < 0.01) by at least 2-fold in at least one of responses to 50 kPa and 50 kPa/NormOx (50 kPa/pO₂ = 21 kPa) in roots of 10 d or 5 d plants. Filled colors represent Log2 fold-change. (B) Venn diagram showing the overlap of significantly changed genes (Log2 fold-change >1, p < 0.01) between responses to 50 kPa and 50 kPa/NormOx in roots of 10 d and 5 d plants. (C) 50 kPa atmosphere associated genes of 5 d/10 d roots with biggest difference in expression level between responses to 50 kPa and 50 kPa/NormOx. The genes with difference more than 1.8-fold were listed.
